Retro Bright and cleaning of the old Arturia midi keyboard

For retro bright, hydrogen peroxide with a concentration of only 5% was used. There was no other one at hand. With such a concentration, it was necessary to illuminate the keys for about a day in a homemade ultraviolet camera.
You can hear music recorded using this instrument in the background. This is what I was missing to record beautiful harmonies, which was very inconvenient using the sequencer keyboard.
